How to configure Editor Options in outlook 2007 using group policy

I have a client that runs into formatting problems when users paste content into an email. The emails are supposed to have a certain look, but sometimes the new content that is pasted in will mess up the formatting.

I would like to use the outlook editor options to make "Match destination formatting" the default choice when users are pasting new content into the update. I have checked the Outlook 2007 administrative template, and the office customization tool and I have been unable to find those options for configuration.

Does anyone know how I could manage these settings in a centralized way? also if anyone knows how to make this setting the default in outlook 2003 that would be greatly appreciated.
